the method for measuring the congestion of noura et al. [a.a. noura, f. hosseinzadeh lotfi, g.r. jahanshahloo, s. fanati rashidi, r.p. barnett, a new method for measuring congestion in data envelopment analysis, socio-economic planning sciences, 44 (2010) 240-246] ,there is no problem for congestion detection in the case of one input and one output but in higher space is not able to detect co...
One of the major issues currently facing developing countries is heavy urban traffic. Growing volumes through traffic often attributed to flow challenges. To improve in city centre, bypass roads or alternative routes are being investigated. These Bypass/alternate divert away from town centers leaving local streets This paper aims explore feasibility such a proposed route serve as an ease conges...
This report investigates the role that public transit can play in reducing traffic congestion. Investigates the role that public transit can play in reducing traffic congestion. This analysis indicates that high quality public transit tends to reduce congestion by attracting travelers who would otherwise drive. As public transit service improves on a corridor (including improved speed, convenie...
Wireless Sensor Networks (WSNs) are a specific category of wireless ad-hoc networks where their performance is highly affected by application, life time, storage capacity, processing power, topology changes, the communication medium and bandwidth. These limitations necessitate an effective data transport control in WSNs considering quality of service, energy efficiency, and congestion control. ...
Congestion is a wasteful stage of the production process where outputs are reduced due to excessive amount of inputs. There are several approaches in data envelopment analysis (DEA) literatures to treat congestion. The concept of strong and weak congestion first developed by Tone and Sahoo [Tone, K., Sahoo, B.K., 2004. Degree of scale economies and congestion: A unified DEA approach. European J...
Urban planning has to perform seismic pathology of urban streets in seismic cities. Streets and roads are the most important spaces and urban elements in the cities which should be considered not only in space occupation and connecting spaces and urban activities but also in seismic vulnerability and on this basis it is planned to reduce environmental hazards and on top of earthquake-related. M...
Green parks are the only natural places for recreation in many metropolitan areas, and European Commission is seeking to improve their air quality and, consequently, citizens’ physical mental health. One of recently adopted approaches achieve pollution abatement these green areas by reducing nearby traffic. In this paper, we analyze impact traffic streets avoid proposing two different approache...
The costs of congestion can be measured using three approaches: the total costs, the marginal costs and the ‘excess burden’. Understanding variation in these measures with particular policies is important for planning and resource management. Assessing the cost distribution (e.g. according to priority routes or urban segments) is key to assessing the delivery of both transport objectives and wi...
This study analyzes the speed of traffic on city streets and level noise from vehicles. In terms objects: To determine amount Nurafshan Nukus in Tashkent, intensity during peak hours was studied. Based results in-kind experiments, following conclusions were drawn: Despite increasing density road network congestion these is very high (more than 2400 cars / hour each side). More 95% moving vehicl...
This paper develops a participatory sensing service, called Fueoogle, that maps vehicular fuel consumption on city streets, allowing drivers to find the most fuel-efficient routes for their vehicles between arbitrary end-points. The service exploits measurements of vehicular sensors, available via the OBD-II interface that gives access to most gauges and engine instrumentation. The OBD-II senso...
